AI Technical Summary

Technical Problem

Traditional oil sludge treatment devices require manual or sensor-based adjustments to the height of the scraper nozzle during the skimming process. This is susceptible to fluctuations in oil layer thickness, waves, or changes in solid content, resulting in low oil recovery efficiency and environmental pollution.

Method used

A floating oil skimming device is adopted, which uses upper and lower limit floats to automatically stick to the oil-water interface to form a floating reference. Combined with the scraper, it scrapes the oil below the oil layer and pushes the oil above, realizing automatic identification of the oil-water interface and efficient oil skimming.

Benefits of technology

Without external power or manual intervention, the oil scraping zone is always locked between the oil and water interface, which greatly improves adaptability and stability, reduces water content, and achieves one-time oil scraping, concentration and temporary storage, reducing the need for subsequent dehydration equipment.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0046] Please refer to Figures 1 to 25The application provides a technical scheme: a hot phase separation sludge treatment heat energy non-condensable gas recycling device, which comprises a treatment box 1, the inner side surface of the treatment box 1 is fixedly connected with an inner frame 2, the outer side surface of the inner frame 2 is fixedly connected with an inner filter screen 21, the inner side surface of the treatment box 1 is fixedly connected with a mounting column 22, the outer side surface of the mounting column 22 is provided with an upper limiting plate 3, the outer side surface of the mounting column 22 is provided with a lower limiting plate 4, the outer side surface of the mounting column 22 is provided with a floating box 5, the outer side surface of the floating box 5 is provided with a scraping plate 6, and the bottom surface of the treatment box 1 is provided with a discharge port 7.

[0047] The oil-water mixture and internal residues in the treatment process are buffered in the treatment box 1, the upper limiting plate 3 and the lower limiting plate 4 are installed in the inner frame 2, large-particle residues are filtered through the inner filter screen 21, contact with the upper limiting plate 3 and the lower limiting plate 4 is prevented, and the inner filter screen 21 intercepts the large-particle residues in the treatment box 1 when water is discharged, so that the large-particle residues cannot be discharged with the water.

[0048] The upper limiting plate 3 comprises an upper floating block 31, the upper floating block 31 is slidably connected with the outer side surface of the mounting column 22, the inner side surface of the upper floating block 31 is fixedly connected with a driving cylinder 32, the output end of the driving cylinder 32 is slidably connected with a lower pressing articulated seat 33, and the two sides of the lower pressing articulated seat 33 are hingedly connected with driven push-pull rods 331.

[0049] The upper floating block 31 is hollow, and the upper floating block 31 is made of foamed polypropylene.

[0050] The upper limiting plate 3 is arranged to determine the upper limit position of the oil scraping area, in the process of “hot phase separation heat energy non-condensable gas recycling” of the sludge, the density of the recovered crude oil is 0.82-0.88 g / cm³, and the recovered crude oil accounts for more than 85 % of the total amount of recovered oil and can float on water.

[0051] The density of foamed polypropylene is 0.02-0.06 g / cm³, which is much lower than that of water and oil, and the foamed polypropylene has good corrosion resistance; the hollow upper floating block 31 has a large volume, and can provide sufficient water discharge capacity to make the upper floating block 31 and the driving cylinder 32 float on the oil.

[0052] The driving cylinder 32 is not directly connected with the lower pressing articulated seat 33, and only presses the lower pressing articulated seat 33 downward when the driving cylinder 32 is extended.

[0053] The lower limit plate 4 comprises a lower floating block 41 which is in sliding connection with the outer surface of the mounting column 22, the outer surface of the lower floating block 41 is fixedly connected with a lower floating shell 42, the inner surface of the lower floating shell 42 is in sliding connection with a piston rod 43, one end of the piston rod 43 is fixedly connected with a piston plate 431, the outer surface of the piston plate 431 is fixedly connected with a rubber pad 432, the top surface of the piston plate 431 is fixedly connected with a traction rope 44, the inner surface of the lower floating shell 42 is fixedly connected with a guide block 441, and the bottom surface of the lower floating shell 42 is in sliding connection with a connecting valve 45, and the outer surface of the connecting valve 45 is provided with an input slot 451.

[0054] The lower floating block 41 and the lower floating shell 42 are made of polypropylene, the piston rod 43 penetrates into the inner surface of the lower floating shell 42, the number of the piston rod 43 is two, the piston rod 43 is hingedly connected with the driven push-pull rod 331, the piston plate 431 and the rubber pad 432 are both in sliding connection with the inner surface of the lower floating shell 42, the two ends of the traction rope 44 are fixedly connected with the piston plate 431 and the connecting valve 45 respectively, and the connecting valve 45 is in sliding connection with the inner surface of the lower floating shell 42.

[0055] Through the setting of the lower limit plate 4, the lower limit position for determining the oil scraping position, in the process of use, the density of polypropylene is between water and oil, which is 0.90-0.91 g / cm³, and is corrosion-resistant, the lower floating block 41 will sink in oil but float on water;

[0056] In the initial state, the piston plate 431 and the rubber pad 432 are at the center position of the lower floating shell 42, at this time, since the lower floating shell 42 is not filled with liquid, air occupies most of the internal space of the lower floating shell 42, so that the whole lower floating shell 42 will float on the oil surface, and the connecting valve 45 will be affected by gravity and will be lowered to make the input slot 451 in contact with the oil layer;

[0057] When the driving cylinder 32 is pressed downward, the two driven push-pull rods 331 will move away from each other to the two sides, thereby driving the piston rod 43 connected thereto to move to the two sides, so that the piston rod 43 will pull the piston plate 431 and the rubber pad 432 apart in the lower floating shell 42, generating negative pressure to suck oil from the connecting valve 45 into the lower floating shell 42, until the driven push-pull rods 331 are horizontally collinear, at this time, the piston rod 43 moves to the limit position on both sides, so that the lower floating shell 42 is filled with oil, the original air in the lower floating shell 42 is replaced by oil, so that the overall density increases, and since the filled oil floats on water, and the density of the lower floating block 41 and the lower floating shell 42 is greater than that of oil, the overall density will be greater than that of oil, and will sink in the oil, and since the density of the sucked oil and polypropylene is less than that of water, it will not sink into the water;

[0058] In the process of moving the piston plate 431 to both sides, the connecting valve 45 will be pulled up by the traction rope 44, and the traction rope 44 will be vertical to the connecting valve 45 due to the passing of the traction rope 44 from the guide block 441, and only bear vertical tension in traction. After being pulled up, the input slot 451 is in contact with the inside of the lower floating shell 42 and is blocked, so that the lower floating shell 42 is sealed to store the inhaled oil inside. The connecting valve 45 has a downward trend due to gravity, but the driven push-pull rod 331 is in a collinear state at this time and cannot be pushed inward. The dead point is used to form self-locking, so as to fix the current position of the connecting valve 45.

[0059] The driving cylinder 32 continues to drive the lower pressing hinged seat 33 to descend, and pushes the lower floating shell 42 into the water and then retracts. Since the driving cylinder 32 is not directly connected with the lower pressing hinged seat 33, the lower floating shell 42 will not be pulled back, and the lower floating shell 42 will float up from the water until it is in contact with the oil layer. Since the oil layer cannot provide sufficient buoyancy, it will not continue to float up, so that the lower floating block 41 and the lower floating shell 42 are located above the water layer and in the oil layer.

[0060] The floating box 5 comprises a lifting frame 51, which is in sliding connection with the outer surface of the mounting column 22. The lifting frame 51 is fixedly connected with connecting side plates 52 at both ends. The outer surface of the connecting side plates 52 is provided with a path groove 521. The inner surface of the path groove 521 is in sliding connection with a contact block 522. One end of the contact block 522 is fixedly connected with a return spring 5221. The lifting frame 51 is fixedly connected with collecting boxes 53 at both sides. The outer surface of the collecting boxes 53 is fixedly connected with trapezoidal blocks 531.

[0061] The top and bottom of the lifting frame 51 are in contact with the upper floating block 31 and the lower floating block 41 respectively. The path groove 521 is composed of a rectangular segment and an arc segment. The bottom of the contact block 522 is provided with an inclined surface. The two ends of the return spring 5221 are fixedly connected with the contact block 522 and the connecting side plate 52 respectively.

[0062] Through the setting of the floating box 5, the oil on the water is scraped. In the process of use, the lifting frame 51 is between the upper floating block 31 and the lower floating block 41. The upper floating block 31 and the lower floating block 41 are located on the oil and the water respectively, so as to limit the lifting range of the lifting frame 51, and make the scraping area exist only in the oil layer area on the water;

[0063] The connecting side plates 52 are used for the connection of the lifting frame 51 and the collecting boxes 53. The collecting boxes 53 store the scraped oil. In the initial state, there is no oil inside, which will float on the oil, but due to the limitation of the upper floating block 31, it cannot further float up, so that the inlet of the collecting box 53 is above the oil layer;

[0064] The connecting side plate 52 controls the scraping path through the contact block 522 and the path groove 521, so that the scraping part is below the oil layer when advancing and does not push the oil layer, and is above the oil layer when returning, so that the oil is scraped into the collecting box 53.

[0065] The scraping plate 6 comprises a fixed hinge seat 61 fixedly connected with the top surface of the connecting side plate 52, an output end of a driving motor 611 fixedly connected with the outer surface of the fixed hinge seat 61, a hinge push-pull arm 62 hingedly connected with the top surface of the fixed hinge seat 61, an active hinge seat 63 hingedly connected with the other end of the hinge push-pull arm 62, a direct-acting scraping plate 64 slidingly connected with the bottom surface of the active hinge seat 63, a scraping plate connecting column 641 fixedly connected with the outer surface of the direct-acting scraping plate 64, a hinge scraping plate 65 slidingly connected with the outer surface of the trapezoidal block 531, and side scraping plates 651 hingedly connected with the two sides of the hinge scraping plate 65 and hingedly connected with a scraping plate sliding seat 6511 at the other end of the side scraping plates 651.

[0066] The output end of the driving motor 611 is fixedly connected with the hinge push-pull arm 62, the hinge push-pull arm 62 is composed of two mutually hinged rods, the active hinge seat 63 penetrates through the direct-acting scraping plate 64 and is slidingly connected with the inner wall thereof, the scraping plate connecting column 641 is slidingly connected with the inner surface of the path groove 521, the scraping plate sliding seat 6511 is slidingly connected with the inner surface of the direct-acting scraping plate 64, the direct-acting scraping plate 64 is in contact with the outer surface of the collecting box 53, and the hinge scraping plate 65 and the side scraping plates 651 are in contact with the trapezoidal block 531.

[0067] Through the arrangement of the scraping plate 6, the oil layer is scraped, in the use process, the driving motor 611 drives the hinge push-pull arm 62 close to one side to swing forward, so that the hinge push-pull arm 62 pushes the direct-acting scraping plate 64 forward through the active hinge seat 63, and the driving motor 611 is reversed to pull it back and also pull the oil layer back;

[0068] In the moving process of the direct-acting scraping plate 64, the scraping plate connecting column 641 is in contact with the path groove 521 to control the moving path, is on one side of the rectangular section when close to the collecting box 53, falls to the lower side under the influence of gravity when moving to the vertical direction, so as to advance below the oil layer and not to push the oil layer until moving to the other end, rises on the arc section to enter the upper side, and is above the oil layer when returning to scrape the oil;

[0069] The scraper connecting column 641 will contact the contact block 522 when rising on the arc segment of the path groove 521. The bottom of the contact block 522 is a slope. When the scraper connecting column 641 contacts, two forces in the upward and inward directions will be generated. The inward force will press the contact block 522 into the inside of the connecting side plate 52, so that the scraper connecting column 641 can pass through. Until the scraper connecting column 641 moves to the upper side of the contact block 522, the contact block 522 is reset under the action of the reset spring 5221. At this time, the scraper connecting column 641 contacts the plane above the contact block 522, only the downward force is generated, and it cannot be pressed in;

[0070] The direct-acting scraper 64 is hingedly connected with the hinged scraper 65 and the side scraper 651, and is slidingly connected with the movable hinge seat 63, can rise and fall on the movable hinge seat 63 to adapt to different heights of the path groove 521. When the direct-acting scraper 64 contacts the collecting box 53, the hinged scraper 65 and the side scraper 651 also contact the trapezoidal block 531. At this time, the direct-acting scraper 64 and the hinged scraper 65 and the side scraper 651 are also trapezoidal in shape. When the direct-acting scraper 64 advances downward, it will drive the hinged scraper 65 and the side scraper 651 to advance at the same time. Until the hinged scraper 65 contacts the inner wall of the processing box 1, the direct-acting scraper 64 will still continue to advance and rise, and the side scraper 651 will be unfolded from the hinged scraper 65, and the scraper sliding seat 6511 can slide on the direct-acting scraper 64 to adapt to the length after unfolding. At this time, the direct-acting scraper 64, the hinged scraper 65 and the side scraper 651 are flat in overall structure.

[0071] When returning, it returns from the upper side and brings the oil back until it contacts the hinged scraper 65 and the trapezoidal block 531. The hinged scraper 65 cannot continue to move, but the direct-acting scraper 64 continues to drive the side scraper 651 to return, so that the side scraper 651 and the hinged scraper 65 are bent into a trapezoidal shape again, and in the process of bending, the oil is pushed to the collecting box 53 on both sides and falls into the path groove 521 below again, realizing the process of scraping on one side.

[0072] The discharge port 7 comprises a transverse block 71 fixedly connected with the bottom surface of the lifting frame 51. The inner side surface of the lower floating block 41 is slidingly connected with a pressing block 711. The bottom surface of the pressing block 711 is fixedly connected with a buffer column 72. The bottom surface of the buffer column 72 is fixedly connected with a valve clamping block 73.

[0073] The transverse block 71 contacts the pressing block 711. The number of the transverse block 71 and the pressing block 711 is two and symmetrically distributed. The pressing block 711 penetrates into the inner side surface of the buffer column 72 and is slidingly connected. The valve clamping block 73 is slidingly connected with the bottom surface of the processing box 1.

[0074] Through the arrangement of the discharge port 7, in the process of use, as the scraped oil in the collection box 53 increases, the floating box 5 and the scraping plate 6 as a whole sink in the water, and the upper floating block 31 and the lower floating block 41 also drop, but cannot drop underwater, and as the oil layer decreases, the spacing between the upper floating block 31 and the lower floating block 41 gradually decreases, until the transverse block 71 on the lifting frame 51 contacts the lower pressing block 711;

[0075] The contact surface of the transverse block 71 and the lower pressing block 711 is a slope, which pushes the lower pressing block 711 to both sides, and pushes the buffer column 72 and the valve clamping block 73 to both sides, and discharges the water after scraping the oil layer, and retains large-particle residues in the treatment box 1 through the inner filter screen 21;

[0076] The transverse block 71 can be lifted inside the buffer column 72, so that different heights of the lower floating block 41 are used.

[0077] In this embodiment, as shown in Figure 1 , Figure 2 , Figure 3 , each component is installed inside the treatment box 1, and the treatment box 1 stores the oil-water mixture and internal residues during the treatment process;

[0078] In this embodiment, as shown in Figure 4 , Figure 5 , large-particle residues are filtered through the inner frame 2 and the inner filter screen 21 to prevent contact with the upper limit plate 3 and the lower limit plate 4;

[0079] In this embodiment, as shown in Figure 6 , the lower floating shell 42 is hollow inside and used to fill air or oil;

[0080] In this embodiment, as shown in Figure 7 , Figure 8 , the traction rope 44 is vertical to the connecting valve 45, and only receives vertical tension when pulled;

[0081] In this embodiment, as shown in Figure 9 , the connecting valve 45 interacts with the outside of the lower floating shell 42 through the input slot 451, and when the input slot 451 is blocked, it cannot interact with the outside, and the lower floating shell 42 forms a closed space;

[0082] In this embodiment, as shown in Figure 10 , Figure 11 , the lower pressing hinge seat 33 is pressed to open the piston plate 431 for extraction, and is separated from the lower floating shell 42 after being retracted;

[0083] In this embodiment, as shown in Figure 12 , the lifting frame 51 is between the upper floating block 31 and the lower floating block 41, and is limited in the range of movement;

[0084] In this embodiment, as shown inFigure 13 , Figure 14 , Figure 15 As shown, the floating box 5 and the scraper 6 are used in conjunction with each other;

[0085] In this embodiment, as Figure 16 , Figure 17 , Figure 18 As shown, the scraper 6 is driven forward and unfolded by the hinged push-pull arm 62, and retracted when returning to press the oil into the collection tanks 53 on both sides.

[0086] In this embodiment, as Figure 19 , Figure 20 , Figure 21 As shown, the scraper 6 advances from below and returns from above;

[0087] In this embodiment, as Figure 22 As shown, the bottom of contact block 522 is a slope, and this surface will be pressed in when subjected to force;

[0088] In this embodiment, as Figure 23 , Figure 24 , Figure 25 As shown, the lower float 41 remains at a constant height above the water, and the lowering of the lifting frame 51 triggers the opening of the discharge outlet 7.

[0089] The method of use and advantages of the present invention: The thermal phase separation oil sludge disposal heat energy non-condensable gas recovery and utilization device operates as follows:

[0090] like Figures 1 to 25 As shown, during use, the sludge enters the treatment tank 1, the inner filter 21 intercepts large particles of residue, and only allows the oil-water mixture to enter the subsequent working area. The floating block 31 always floats on the top surface of the oil layer due to its extremely low density, providing the "upper limit for oil scraping" for the entire system. The drive cylinder 32 floats together with the floating block 31, and the output end extends downward to press down the lower hinge seat 33. The lower hinge seat 33 simultaneously pushes the two driven push-pull rods 331 outward for the subsequent oil suction and sinking of the lower limit plate 4.

[0091] Since the lower float 41 and the lower float housing 42 have a density between water and oil, they initially float in the oil. The piston rod 43 is pulled outward by the driven push-pull rod 331, and the piston plate 431 + rubber pad 432 moves outward, generating negative pressure inside the lower float housing 42. The connecting valve 45 is drawn open by the negative pressure, and oil enters the lower float housing 42 through the input groove 451. At the same time, the traction rope 44 lifts the connecting valve 45 and locks it, closing the valve. After the housing is filled with oil, the overall density is greater than the oil density, and the lower float housing 42 descends to the "water-oil" interface, providing the system with the "lower limit for oil scraping".

[0092] The lifting frame 51 is limited between the upper floating block 31 and the lower floating block 41, and can only move up and down within the oil layer height on the water surface. The collecting box 53 floats with the lifting frame 51, and keeps the inlet above the oil layer when the inside is empty, ready to receive the scraped oil. The path groove 521 (rectangular section + arc section) connected with the side plate 52 and the contact block 522, together with the reset spring 5221, determine the "dive and rise" trajectory of the scraping plate 6.

[0093] The fixed hinge seat 61 and the driving motor 611 provide reciprocating power, the hinge push-pull arm 62, the movable hinge seat 63 and the direct-acting scraping plate 64 move along the path groove 521. When the direct-acting scraping plate 64 advances, it dives below the oil layer, and when it returns, it back scrapes above the oil layer, pushing the oil to the collecting box 53. The hinge scraping plate 65, the side scraping plate 651 and the scraping plate sliding seat 6511 are linked with the trapezoidal block 531 to realize the continuous deformation of trapezoidal-plane-trapezoidal, ensuring that the oil is effectively pushed into the collecting box 53 on both sides.

[0094] As the oil in the collecting box 53 increases, the floating box 5 sinks as a whole, the horizontal block 71 at the bottom of the lifting frame 51 presses against the lower pressing block 711, the inclined surface causes the valve clamping block 73 to move outward, opening the drainage channel. Water is discharged through the discharge port 7, and residues are intercepted by the inner filter screen 21. When the oil layer is completely scraped off and the water level is lowered, the horizontal block 71 and the lower pressing block 711 are separated, the valve clamping block 73 is opened, and the water is drained to retain the particulate residues inside the treatment box 1, completing a working cycle.
